Byte 6: Operation status

This byte stores information about actuator movement.
Value Description
1 The actuator is in off-time (e.g. reversing prevention time).
0 No signal
1 The actuator is in an intermediate position e.g. neither in end position OPEN nor in
end position CLOSED.
0 No signal
1 The actuator is within the set stepping range.
0 The actuator is outside the set stepping range.
No signal (reserved)
1 Actuator is running (output drive is moving)
Hard wired collective signal consisting of signals:
(26) Bit: Running LOCAL
(27) Bit: Running REMOTE
(28) Bit: Handwheel oper.
0 No signal
1 Output drive rotates without electric operation command.
0 No signal
